Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31573346, here are decompositions:

67 + 31573279 = 31573346
157 + 31573189 = 31573346
193 + 31573153 = 31573346
223 + 31573123 = 31573346
367 + 31572979 = 31573346
397 + 31572949 = 31573346
523 + 31572823 = 31573346
577 + 31572769 = 31573346

Showing the first eight; more decompositions exist.
